Calc: From 1 Different Sources
(calci-, calco-) combining form denoting calcium or calcium salts.
A concretion formed in any part of the body usually compounds of salts of organic or inorganic acids... calculus
The heel-bone or os calcis, and the largest bone in the foot.... calcaneus
This is an outdated term for ergocaliciferol or vitamin D2 (see APPENDIX 5: VITAMINS).... calciferol
Abnormal deposition of CALCIUM in the body tissue.... calcinosis
A hormone, produced by the THYROID GLAND, which is involved in the metabolism of bone. Acting to lower concentrations of CALCIUM and PHOSPHATES in the blood, calcitonin is given by injection in the treatment of some patients with HYPERCALCAEMIA (especially when associated with malignant disease). In severe cases of PAGET’S DISEASE OF BONE it is used mainly for pain relief, but also relieves some of the neurological complications such as deafness.... calcitonin
Calcicosis is a traditional term applied to disease of the lung caused by the inhalation of marble dust by marble-cutters.... calcicosis
The general name given to concretions in, for example, the URINARY BLADDER, KIDNEYS or gall-bladder (see LIVER).... calculi
A branched renal stone formed in the image of the collecting system of the kidney (see KIDNEYS). It ?lls the calyces and pelvis and is commonly associated with an infection of the urine, particularly Proteus vulgaris. The calculus may lead to pyonephrosis and an ABSCESS of the kidney.... staghorn calculus
A derivative of vitamin D, used in topical preparations for treating the skin disorder psoriasis.... calcipotriol
The deposition of CALCIUM salts in body tissues, normally BONE and TEETH, though abnormal deposits can occur in damaged muscles or the walls of arteries.... calcification
Calcium; this powdered mineral is often added as a supplement to herbal and other medicinal preparations and is often used in the treatment of anemia.... calcio
A salt of the element CALCIUM used to treat de?ciency of the mineral or to prevent osteoporosis (see BONE, DISORDERS OF). Tablets can be obtained without a doctor’s prescription. It is used intravenously to treat low calcium levels causing symptoms in newborn babies.... calcium gluconate
Calculi relating to kidney... renal calculi
The deposition of calcium salts in developing teeth. Primary teeth begin to calcify in a fetus at between 3 and 6 months gestation; calcification of permanent teeth (other than the wisdom teeth) begins between birth and 4 years. Abnormal calcification occurs in amelogenesis imperfecta, an inherited disorder of the enamel (see hypoplasia, enamel), and can also result from the absorption of high levels of fluoride (see fluorosis).... calcification, dental
A hard, crust-like deposit (also known as tartar) found on the crowns and roots of the teeth. Calculus forms when mineral salts in saliva are deposited in existing plaque. Supragingival calculus is a yellowish or white deposit that forms above the gum margin, on the crowns of teeth near the openings of salivary gland ducts. Subgingival calculus forms below the gum margin and is brown or black. Toxins in calculus cause gum inflammation (see gingivitis), which may progress to destruction of the supporting tissues (see periodontitis). Calculus is removed by professional scaling. Attention to oral hygiene reduces recurrence.... calculus, dental
a drug used, in conjunction with counselling, for the maintenance of sobriety. Patients must already be abstinent at the beginning of treatment. The most common side-effect is diarrhoea.... acamprosate calcium
n. a spurlike projection. The calcar avis is the projection in the medial wall of the lateral ventricle of the brain.... calcar
drugs that act by inhibiting the calcium-dependent protein *phosphatase calcineurin, an enzyme that initiates a sequence of events that bring about activation of T *lymphocytes. The group includes *ciclosporin and *tacrolimus, which are major maintenance immunosuppressants used in transplantation. Topical calcineurin inhibitors (e.g. tacrolimus, pimecrolimus [Elidel]) are used in the treatment of eczema when topical steroids have failed or are contraindicated. Stinging is a common transient side-effect, and reactivation of infections may occur.... calcineurin inhibitors
n. calcific uraemic arteriolopathy: a rare and often fatal complication of end-stage renal failure associated with small vessel calcification, intractable skin ulceration, and a high risk of septic complications.... calciphylaxis
n. 1,25-dihydroxycholecalciferol: the final and most metabolically active form of vitamin D3. It is formed in the kidney by the addition of two hydroxy (?OH) groups to the basic vitamin D molecule, which itself is produced in the skin from 7-dehydrocholesterol or ingested in certain foods. Calcitriol is given to raise blood calcium levels in patients with severe kidney disease and to treat postmenopausal osteoporosis. It is also used as an ointment to treat psoriasis.... calcitriol
(calcium antagonist) a drug that inhibits the influx of calcium ions into cardiac and smooth-muscle cells; it therefore reduces the strength of heart-muscle contraction, reduces conduction of impulses in the heart, and causes *vasodilatation. Calcium-channel blockers, which include *amlodipine, *diltiazem, *nicardipine, *nifedipine, and *verapamil, are used to treat angina and high blood pressure.... calcium-channel blocker
a condition in which calcium pyrophosphate is deposited in joints. The most common manifestation is *pseudogout, marked by acute pain, redness, and swelling resembling gout. Alternatively it may be asymptomatic in association with *chondrocalcinosis seen on X-ray, it may occur with osteoarthritis in the affected joint, or there may be chronic inflammation of the joint.... calcium pyrophosphate deposition disease
a quantification of the amount of calcium seen in the coronary arteries on a CT scan, calcium being a marker of severe coronary artery disease.... calcium score
n. the presence of multiple calculi (stones) in the body. See calculus.... calculosis
the calcification of injured or necrotic tissue in the absence of systemic *hypercalcaemia. Dystrophic calcification is a characteristic feature in some cancers of the breast, ovary, and thyroid gland. Compare metastatic calcification.... dystrophic calcification
the calcification of otherwise normal tissues in patients with *hypercalcaemia. Compare dystrophic calcification.... metastatic calcification
see calcineurin inhibitors.... topical calcineurin inhibitors
